MACHINE FOR MANUFACTURING PAPER PAILS.

SPECIFICATION forming part of Letters Patent N 0. 455,718, dated July 7, 1891.

Application filed September 17, 1890. Serial No. 365,268. (No model.)

To all whom it may concern:

Be it known that we, UZAL HULL and \VIL- LIAM W. McEwAN, citizens of the United States, and residents of Belvidere, in the county of lVarren and State of New Jersey, have invented certain new and useful Improvements in Machines for Manufacturing Paper Pails; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a vertical central section through the device, showing the parts in operative position. Fig. 2 is a top plan view of the same, showing the lever-- clamp. v

This invention has relation to means for facilitating the manufacture of paper pails; and it consists in the novel construction and coinbinations of parts, being in some respects an improvement on the construction shown in the patent issued to us on November 11, 1890, No. 440,594, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the base-block or press-head, the top a of which is of hollow concave form, and is provided with drainage-channels converging to a central opening leading to a drainpipe A.

Upon the concave top of the base-block is placed the wire-cloth concave guard and strainer-piece O, and this guard is held in position upon the base-blockA by means of the inward flange Z) of the removable holder B, which is of stout metal, and is designed to receive the wet paper tubular blank of which the pail is to be formed. Before the paper tube is placed upon the holder the cloth guard c is placed over the wire-cloth piece 0 to prevent the particles of pulp from entering the meshes thereof and closing the same. This cloth piece also prevents the bottom of the pail from adhering to the wire-cloth.

. The tubular paper blank is indicated at D. It is designed to be placed upon the holder 13, and it has an upward extension above the top of the same, said extension being designed to be saturated and bent downward and centrally upon the top of the base-block or presshead, where it is punctured with a needle-inhomogeneous character, its particles being prevented from adhering to the wire cloth strainer by means of the cloth guard c.

H'indicates a cloth binder, which is placed the bottom of the pail, and said binder serves to prevent the particles of the pulp from adhering to the wire-cloth strainer of the follower K, so that said strainer is kept clear.

vex face, which is channeled and provided with a wire-cloth strainer, and said follower is designed, when the parts are placed in the press, to descend upon the soft mass on the therefrom while giving it form and consistency, so that a suitable bottom shall be provided for the pail.

In order to hold the parts in position, an exjacket is cleft, and is formed with the perforated neck portion f around the follower and with the drain-channels f around the skirt portion. It is also provided with a leverings, is fastened on closing, the position of its parts being such as to hold it in looking position until the handle is operated to release them. This lever-clamp consists of the anglepivoted between lugs 70 near one of the meeting edges of the jacket and its other arml forming a handle portion. A slightly-curved arm-or link is pivoted to the angle of the le- 70', near the opposite meeting edge of said 3' acket, so that as the said lever is brought down to the position shown in dotted lines in Fig. 2 it will clamp said jacket securely in place.

right angles to the jacket, they afford a convenient means for moving the base-block and the parts connected therewith from under the drop to the press and back again without loss strument and worked into a 'pulpy mass of over the pulpy mass which is designed to form The follower K is usually formed. with a contop of the base-block and express the water terior jacket or bandage F is provided. This .75

clamp L L, which, as indicated in the drawlever L, having one end of its shorter arms ver at one end and at its other end to the lugs As the handles of the lever-clamp project at of timea matter of great importance in oproo tion, with the base-block, the Wire strainer,

having the hollow concave top and the drainage-channels converging; to a central opening in saidtop, and the covering therefor, of the follower having the channeled convex face, the removable holder, the exterior cleft jacket or bandage having the perforated neck portions, and t-he'draining-ehannels and the lever-clamp or fastening for said jacket, substantially as specified.

In testimony whereof We affix our signatures in presence of two witnesses.
